ALEX Lesson Plans Subject: Mathematics (9 - 12) Title: Interpreting Functions Description: During this lesson, students will be introduced to interpreting functions.  A function is a relationship between two sets:  the domain (input values) and the range (output values). Thinkfinity Lesson Plans Subject: MathematicsTitle: Graph Chart      Add Bookmark Description: This reproducible transparency, from an Illuminations lesson, contains the answers to the similarly named student activity in which students identify the independent and dependent variables, the function, symbolic function rule and rationale for a set of graphs.Thinkfinity Partner: IlluminationsGrade Span: 9,10,11,12Subject: MathematicsTitle: Graphing What       Add Bookmark Description: This reproducible activity sheet, from an Illuminations lesson, is used by students to record independent and dependent variables as well as the function and symbolic function rule for a set of graphs.Thinkfinity Partner: IlluminationsGrade Span: 9,10,11,12Subject: MathematicsTitle: Tube Viewer Simulation      Add Bookmark Description: This student interactive, from Illuminations, simulates the effect of viewing an image through a tube. As students move the location of the person or change the length of the tube, the image and measurements also change.Thinkfinity Partner: IlluminationsGrade Span: 9,10,11,12Subject: MathematicsTitle: Gallery Walk      Add Bookmark Description: In this lesson, one of a multi-part unit from Illuminations, students view the work of other students in the class and explain their own work. Students move from graph to graph during this time and, without any talking, view the work of their classmates. While on their Gallery Walk, the students think about the data their classmates plotted and whether or not the information accompanying each graph seems appropriate. Each pair of students then stands next to their own work and explains one of the graphs.Thinkfinity Partner: IlluminationsGrade Span: 9,10,11,12
